At where I work we are using NX version 6.0
We machine molds w/ multiple cavities
When finish milling the sidewalls of the cavities
we usually select the surfaces of one of the cavities
then translate the toolpath to the other cavities using
transform/rectangular array/instances
this procedure usually works well for us.

Where my questions comes in is if I go back into the original operation
to edit any parameters, this statement "pops" on the screen
"All instances of this operation will be edited"
and when I regenerate the operation it looks as if all the instanced
operations also get regenerated. But after a closer look I have discovered
that instanced operations HAVE NOT changed ,that in fact they still have
the original toolpath.

To get around this problem I delete the instanced operations then re-translate the operations.

Can someone please tell me how come the instanced operations are not updating when UG tells me that "All the instanced operations WILL be
updated."

Thanks ,
Brian

Make sure your manufacturing preferences are set to update all instances and generate tool paths is active.
